Bunches of Functions for Sequences

• Basic list manipulation
  • insert-before() and remove()
  • reverse()
  • index-of()
  • distinct-values()
  • subsequence() — like substring() for sequences
• Test cardinality in sequences
• deep-equal() (are these sequences pair-wise really, really equal)
• Perform math on items in a sequence
  • count()
  • average()
  • max()
  • min()
  • sum()

As well as sequence generation functions dealing with IDs and IDREFs, document availability testing, and document collections
